Spiral Galaxy - ICM Interactions in the Virgo Cluster
We discuss HI and optical evidence for ongoing ICM-ISM interactions in 6 HI-deficient Virgo cluster spiral galaxies. One of the clearest cases is the highly inclined Virgo galaxy NGC 4522, which has a normal stellar disk but a truncated gas disk, and lots of extraplanar gas right next to the gas truncation radius in the disk. Unusually strong HI, Hα and radio continuum emission are all detected...
متن کاملThe dwarf galaxy population of the Virgo Cluster
I review the status of knowledge about the dwarf galaxies in the Virgo Cluster (VC) concentrating on work published after 1995. I explain the present ideas about the nature and history of the dwarf elliptical galaxies and emphasize the major increments in understanding achieved in the study of the dwarf irregular population. Special attention is given to the samples of late-type dwarf galaxies ...

متن کاملNGC 4254 : a spiral galaxy entering the Virgo cluster
Deep Effelsberg Hi spectra of the one-armed, bright Virgo cluster spiral galaxy NGC 4254 are presented. Five different positions were observed in the 21 cm Hi line with the Effelsberg 100-m telescope: one in the center and 4 located one HPBW to the NE, NW, SW, and SE, respectively, from the galaxy center. The spectra are compared to existing deep VLA observations, and the single dish and interf...
متن کاملThe Virgo Consortium: the Evolution and Formation of Galaxy Clusters
We report on work done by the Virgo consortium, an international collaboration set up in order to study the formation and evolution of Large Scale Structure using N–body simulations on the latest generation of parallel supercomputers. We show results of 256 particle simulations of the formation of clusters in four Dark Matter models with different cosmological parameters. Normalizing the models...
